So I took my charger with me to class today because my phone was almost dead. As it was charging I began to fiddle with it ex: go on reddit :P. Suddenly The phone began to lag and the screen shut off. I unplugged it and began to hold down the power button.... Had it held down for about a minute and still no results. The charging light is stuck green even when off the charger and the navigation buttons are stuck on. When holding down the power button the navigation buttons would also flash as it normally does but im not getting any feedback from the device. Anyone have any solutions? I need my phone to be working asap. If there isnt any hope i may as well upgrade.
